Well, that's what /proc/parport/0/hardware sais:
base: 0x378
irq: 8
dma: none
modes: SPP,ECPEPP,ECPPS2
And on booting I get:
<6>parport0: PC-style at 0x378, irq 8 [SPP,ECPEPP,ECPPS2]
<6>parport0: no IEEE-1284 device present.

On a second thought, seems like it still uses polling, even if it
lists the irq in /proc. The counter in /proc/interrupts doesn't
increase when I print something:
CPU0
0: 12095045 XT PIC timer
1: 110379 XT PIC keyboard
2: 0 XT PIC cascade
3: 7 XT PIC serial
4: 1863925 XT PIC serial
5: 248340 XT PIC SoundScape
8: 0 XT PIC parport0
9: 2 XT PIC SoundScape
11: 1909153 XT PIC aic7xxx
12: 517581 XT PIC PS/2 Mouse
13: 1 XT PIC fpu
15: 42328 XT PIC ide1
NMI: 0
Only "parport0" changed to "lp" and back a few times while it was printing
:)
